/**
* Creates an Observable that emits some values you specify as arguments,
* immediately one after the other, and then emits a complete notification.
*
* <span class="informal">Emits the arguments you provide, then completes.
* </span>
*
* <img src="./img/of.png" width="100%">
*
* This static operator is useful for creating a simple Observable that only
* emits the arguments given, and the complete notification thereafter. It can
* be used for composing with other Observables, such as with {@link concat}.
* By default, it uses a `null` IScheduler, which means the `next`
* notifications are sent synchronously, although with a different IScheduler
* it is possible to determine when those notifications will be delivered.
*
* @example <caption>Emit 10, 20, 30, then 'a', 'b', 'c', then start ticking every second.</caption>
* var numbers = Rx.Observable.of(10, 20, 30);
* var letters = Rx.Observable.of('a', 'b', 'c');
* var interval = Rx.Observable.interval(1000);
* var result = numbers.concat(letters).concat(interval);
* result.subscribe(x => console.log(x));
*
* @see {@link create}
* @see {@link empty}
* @see {@link never}
* @see {@link throw}
*
* @param {...T} values Arguments that represent `next` values to be emitted.
* @param {Scheduler} [scheduler] A {@link IScheduler} to use for scheduling
* the emissions of the `next` notifications.
* @return {Observable<T>} An Observable that emits each given input value.
* @static true
* @name of
* @owner Observable
